Sigh. Yes I was mistaken. I failed so see the term "cross-compilation
tools..." and I had forgotten that --host was what I used when cross
compiling Samba and netatalk and Avahi and ... on Fedora 9 x86_64 or
whatever for Marvell ARM Linux.

Well, yes and no. For example:

You suggested ./configure --host=arm-linux --prefix=/home/hitesh/samba/samba-05

However, --prefix has to be correct as well, as it is the location
that the built programs are going to reside on the 'target' and he
should probably use something --prefix=/usr/local or --prefix=/opt or
whatever path he wants on the final target, and then when moving
things to the staging directory, use 'make install
DIR=/path/to/staging/dir' (I have forgotten the actual magic
incantation so that is only approximately correct). This is because he
is most likely then going to have to package up everything for
inclusion in EEPROM/Flash. Even if he is going to put it on a disk on
the target, he will not want '/home/hitesh/samba/samba-05' embedded in
everything because that will likely not exist on the target.

So, it's not rocket science, but it does require careful thinking
about what is to happen, and it took a while to get it correct, so I
built scripts to encapsulate the steps for the approximately 10
packages I was cross compiling ...
